Description

TOUCH-FREE FLUID-APPLI CATION DEVICE

The invention relates to a non-contact fluid application device, which is particularly suitable for improving hygiene. Hygiene is a particularly relevant topic, especially in the medical field: between 400,000 and 600,000 people are still infected each year in Germany with pathogens during a stay in a hospital. Up to 30,000 people die as a result of these sometimes very serious infections. It is believed that up to 90% of these nonso-comial infections are transmitted by the hands. For this reason, hygienic hand disinfection is one of the most important measures for the prophylaxis of nosocomial infections in particular and / or infectious diseases in general. The goal of hand disinfection is primarily to prevent the spread of hand-held pathogens.

The transmission of infectious diseases (bacteria or viruses) takes place predominantly via droplet infection or smear infection. However, hands play a crucial role in both transmission paths. Hand disinfection therefore not only affects the medical sector, such as hospitals, practices and other medical facilities, but also all areas where people come into direct or indirect contact with each other.

Due to recent infectious diseases such as swine flu and avian influenza and their presence in the media, there is a shift in people's perceptions of sanitary measures: hand disinfection has made the leap from the hospital to the end-consumer area perceived as a suitable precautionary measure by a large part of the population. Hand sanitizers are generally offered in dispenser bottles in the free trade and specialized trade. The application of the hand disinfectant

CONFIRMATION COPY on the hand via mechanical dosing or simply by dropping the agent on the hand. About 3 ml of the product are applied to the palm of the hand and are then to be rubbed over a time specified by the manufacturer (contact time) between the hands and fingers. The problem here is the partially insufficient wetting of the skin z. B, between the fingers and under the fingernails by the user.

This problem is minimized by automated dispensing systems in which the application is carried out by automatic spraying of the preparation. The user holds both palms in relation to a sensor of an automated dispenser device, after which the sensor initiates the spraying of a well-defined amount of hand sanitizer onto both palms of the user. In addition to disinfectants, however, metering devices for other fluids such as care products and cream lotions from the prior art are well known. Simple dosing devices work with manually operable pumps and deliver a dose of the fluid after a pumping stroke. DE 10 2009 008 022 A1 discloses a metering dispenser which allows to remove a predetermined amount of a fluid. There, a hygiene fluid container is equipped with a metering device which is manually adjustable and permits metered dispensing of the hygiene fluid. Further, various dosing devices are known from the prior art, which may be secured by a housing attached to a wall or may be integrated into a surface surrounding a washing device. Common to these dispensers are pumping devices that are activated manually, usually by means of a lever or push button, to dispense a more or less liquid substance. The pumping device is often realized as a piston pump. Another dispenser for soap, hand lotion, disinfectant or the like is described in DE 35 05 893. The dosage is carried out by means of a peristaltic pump, wherein the promotion of the liquid is effected by mechanical crushing of the tube by means of a handle.

There are also metering devices that allow the non-contact dispensing of the dosing. Such devices are disclosed in DE 35 31 385 and DE 101 03 890. Non-contact dispensing serves to prevent germ transmission during activation of the dispenser. Such non-contact devices can be triggered by sensors, in particular by means of opto-electronic sensors, such as the disclosed in WO2004 / 054460 A3 device for dispensing disinfectants and cleaning agents.

Furthermore, there are already devices for disinfection, which also make it possible to dispense both disinfectant and manual cleaning means sensor-controlled and at the same time absorb excess liquid. WO2004 / 054460 A3, for example, describes a device for cleaning and / or disinfecting hands, which consists of a housing with a tunnel, on the wall of which a sensor and a spray nozzle for dispensing liquids are arranged. The sensor triggers a connected to the nozzle pump, which is connected to a reservoir. The tunnel has a bottom sloping down to the rear wall, below which there is a drawer for collecting liquid draining from the tunnel wall, in which an absorbent is additionally introduced in order to bind the excess medium. The amounts of disinfectant to be dispensed from the nozzle are prescribed and amount to about 1, 5 ml, which is sufficient for simple purposes.

Disadvantages of these devices can be seen in the fact that they are all used inflexible and in terms of their design are either bound to a particular Vorratsgehälterform so that a sensor-based dispenser head can be mounted safely; or that they are very simple, so that a simple delivery hose can be guided into any storage vessel, these embodiments being less secure in handling and arrangement and possibly forming an overall arrangement which has little is speaking and thus does not encourage a user to use.

Based on this prior art, it is desirable to provide a metering device for the application of fluids, in particular for disinfection, on the one hand automated operable and on the other hand flexibly usable for different device vessels and still has an animating for use form.

This object is achieved by the fluid application device having the features of independent claims 1 and 2.

Preferred developments are described by the subclaims.

In a first embodiment, the automatic fluid delivery fluid application device according to the invention relates to a device comprising at least one application head equipped with one or more sensors and a nozzle through which fluid can be dispensed. The nozzle is fluidly connected to a reservoir. The application head has on its upper side an output arm, on which the nozzle is arranged pointing downwards. The reservoir is in this embodiment of the invention, a pressurized vessel, such as a pressure box, which, or the, an outlet, which can be opened and closed by a valve. A control unit is present in the application head in order to trigger the opening and closing of the valve in a sensor-controlled manner. The valve is connected to the nozzle via a connecting piece, so that the fluid can be dispensed via the nozzle when the sensor causes the opening of the valve with a corresponding opening means. Further, an inventive pressure vessel adapter piece is provided on the application head, which serves to hold the pressure vessel to the application head and can hold the various pressure vessel cans.

This embodiment of the invention makes it possible, without the supply of ex- Energy to pump the fluid from the reservoir to the nozzle to make the fluid output. It is only a very small amount of energy required to operate the sensor. As a result, this device can basically be operated battery-powered, it can therefore be used independently of a mains supply.

In another embodiment, the automatic fluid delivery fluid delivery device, which also includes an application head having a sensor and a nozzle for dispensing fluid, may be configured such that the sensor is connected to a pump connected to the reservoir and connected to the nozzle , is operatively connected. Furthermore, this application head has on its upper side an output arm, on which the nozzle is arranged pointing downwards, wherein in this embodiment a motor-driven pump controllable by the sensor is arranged with an inlet and an outlet for fluid in the application head. The pump is connected via a valve on the output side by means of a hose or pipe connection and with a connection nozzle of the nozzle, or a connecting piece, for dispensing the fluid. Further, the pump is disposed over an adapter piece and can be connected to this fluid-tight with a storage vessel.

In this case, the adapter piece can be permanently or detachably arranged on the application head. This takes place via the lower or inner side of the adapter piece, which can be brought into engagement with a storage vessel opening, so that a delivery device, in particular a hose or a tube, extends from the inlet side of the pump into the storage vessel.

The adapter piece can be designed so that its upper side can be positively connected to the application head and its underside has a flange, in particular a flange which is offset inwardly from an edge of the adapter piece and which can be brought into engagement with the opening of the storage vessel, by the flange engages around a reservoir neck or immersed in this. A delivery hose extends from the input side of the pump by an opening provided in the adapter piece into the storage vessel, so as to promote the fluid to actively become the sensor out.

The activation of the sensor in the embodiments according to the invention takes place by the introduction of a body part, in particular a hand, or alternatively a foot, into the detection area of the sensor

The sensors which are particularly suitable for the fluid application device according to the invention according to both embodiments are optical or opto-electronic sensors. The application device can be equipped with a plurality of sensors, but at least one sensor is arranged on the output arm facing either down or on the application head in the direction of the nozzle, so as an activating hand, which is guided under the nozzle, in each case to detect. To advantageously determine a hand shape or a foot shape, the sensor can measure reflection. In the reflection measurement, it is even possible to perceive wrinkles in the body skin and to deduce from the depth of wrinkles the need for disinfectant or care fluid which is dispensed by the application device. It is also possible to provide a plurality of sensors on the delivery arm and / or the vertical wall of the application head to determine a more accurate determination of the size and body part shape of the body part to be fluidized. In the variation of the embodiment in which the fluid must be pumped, that is, the sensor is operatively coupled to a pump so that the triggering by the sensor causes the pump drive to operate, a diaphragm pump operating on the output side with a one-way valve is preferred is coupled. The membrane pump has to be supplied by a power supply unit, although this may be a mains supply by means of a power line known to the person skilled in the art and corresponding components, but preferably a battery packageable in its entirety may be used. is to be provided, which is accordingly in electrical contact with the pump. The design as a magazine or cartridge eliminates the annoying replacement of individual batteries and the entire magazine can be advantageously removed with a handle from the fluid application device. Particularly advantageously, the application head can be opened for this purpose, for example by the provision of an apparent head cover.

The one or more sensors is / are operatively coupled via a control and / or control unit to the pump, which may be arranged on a circuit board. Thus, it is possible to preset the output volumes of the fluid on the one hand or to regulate the other depending on the shape, size, skin fold depth or other control parameters.

In the embodiment in which the storage vessel is a pressure cell, the control unit is used to control the valve, but it can also be designed as a control and regulation unit, also to an output quantity of a fluid depending on the hand size, shape and the other parameters mentioned regulate. In this case, graduated ml graduations of 0.5 in half milliliter stages ascending to about 3.0 ml, but it is also possible here to adjust the valve opening time infinitely. Likewise, however, in the variant in which a pump stroke is made, also take place a nearly stepless adjustment.

In the variant in which a delivery hose connects the pump to the storage vessel and wherein the delivery hose is passed through the opening of the adapter piece, can be provided as a perforated plug, in particular a plug with double hole guide in the adapter piece, through which the delivery hose sealing in the Opening is attached. Advantageously, the fluid application device, in particular arranged in the application head, a device for measuring the density of the fluid, and / or a device for hand and skin texture recognition, as already by the sensors explained, or alternatively or additionally, a device for determining the size of the hand, which can also be realized by said sensors. The hand size or skin condition determination devices are operatively coupled to the control and / or regulating device for the pump or valve, respectively.

The fluid application device according to the invention can also be designed so that the adapter piece is formed as a union nut and connected to the application head. This design is particularly useful because the nut can be screwed on virtually any bottle size with neck external thread; if necessary, the adapter piece with union nut can be selected accordingly and replaced on the application head. Space saving and aesthetically, the conveyor there is a double-walled conveyor pipe, in particular a coaxial feed pipe whose inner tube forms the battery magazine, which is electrically connected to the energy supply at least with the pump, in particular with the pump and one or more present in the application head energy consumers. In addition, a storage bottle of disinfectant or other fluid equipped with this application device can be placed in a holder to improve stability.

Both the pressure vessel adapter piece for pressure cans, as well as the adapter piece for non-pressurized bottles or vessels may extend into a shell piece, or a housing, which surrounds at least a portion of the storage vessel. Thus, the device is visually attractive and can perform additional functions for attachment or stabilization or include elements to fulfill tasks such as stabilization or wall mounting or more. In the case of a fluid application device provided for the wall arrangement, the jacket piece may be designed in such a way that it is open on its side facing the wall or on the bottom side, in order thus to prevent the insertion of the projection. to allow storage container. The wall mounting can be done via a Wandhaiterung. Incidentally, the shell piece may also be formed integrally with the Wandhaiterung. Further, for flexible use of the device, the shell piece or the integrally formed with this Wandhaiterung inside have a lift device, which consists of a footprint for the storage vessel and a rail element, so that the footprint forms a vertically displaceable bottom of the shell piece. This small bottles can be easily placed on the footprint and drove to the adapter piece.

As an alternative to wall mounting, a screw clamp can be attached to the wall holder, so that the application device can advantageously be arranged on a horizontal support arm or a piece of furniture with a horizontally oriented attachment surface.

Furthermore, especially when the fluid application device is designed as a stationary element, the jacket piece can be open on the sensor side or on the actuating side, so that the storage container can be inserted or inserted from the front. Again, in the variation as a stand component, the insertion of a storage vessel can be done from below, so that there is also the possibility of making the shell piece so that it completely surrounds the storage vessel circumferentially. In this case, a front portion of the shell piece of the facing to the hand peripheral portion of the storage vessel, articulated hinged and be articulated via a hinge which is present at this part and the lower edge of the shell piece. It can be pushed from below instead of the articulated arrangement by a design with a pair of rails with each corresponding elements on the two Mantelstück- and front section edges. In one embodiment, the jacket piece extends as a particularly shapely application device, preferably as far as the lower edge of the storage vessel or beyond. At the lower edge of the shell piece, a drip tray may be provided which extends thereunder according to the extent of the dispensing arm to receive excess fluid. This may be necessary if the operator of the application device triggers two dispensing operations, for example, and notes that too much fluid is being dispensed and the hand is pulling away. Especially in the case of disinfectants, which may be alcoholic or aggressive and thus can lead to annoying and unwanted vapors, the drip tray can serve well.

In one embodiment, the drip tray may have a height. In this case, the upper floor has a plurality of passage openings in order to drain the fluid, wherein the passage openings may preferably be provided at the edge of the drip tray. At the lower bottom, a suction device, such as a driven for suction rotor, which is in fluidic contact with the passage openings, the excess liquid is sucked directly through the passage openings downwards.

Advantageously, therefore, one or more absorption media for fluid is arranged on or in the lower bottom of the double or multiwall element. Instead of a double bottom, a holding structure for an absorbent such as a pad can simply be attached here. These can be either known particulate absorbents, but also a nonwoven or a suction pad, depending on how the chemical nature of the fluid to be dispensed.

The collecting drip tray can, which is advantageous in particular for cleaning, be detachably arranged on the casing piece. Alternatively, however, the drip tray may also be integrally formed with the shell piece. In a further embodiment, the drip tray has an attachment point at the attachment point. drip tray on the shell piece on a passage for a power supply line, which is required when the suction rotor with a power line and not operated by battery power, or is supplied. ^{Of course} , it is also conceivable here to supply such a suction device with low energy and battery power, it being possible to provide a receiving device for batteries in the front section and a corresponding electronic coupling to the suction device. Again, batteries can be stored in magazines to facilitate reloading.

In yet another embodiment, the drive of the suction device to the sensor, which triggers either the valve opening or the pump operation, communicatively and operatively connected. The connection can also be made with the interposition of the control and / or regulating unit, so that directly with the triggering of the pump or the opening of the valve and thus the fluid output and the suction is set in motion, so as to avoid that when starting the output process initially excess fluid, which optionally also rebounds from the hands, exits into the ambient air. In one embodiment of the fluid application device, which uses a pressure vessel and an outlet with valve as the reservoir, the pressure vessel adapter piece can be configured such that the pressure vessel holds by means of a clamping holder. In particular, the clamping holder can be designed such that at least two Umgriffele- each biased by a clamping spring, which are arranged radially displaceable in a frame part, exert pressure against the vessel and hold it in this respect. In this case, the clamping springs can either be supported on the outside against a special attachment, in which the clamping bracket is arranged. This attachment can be docked in the application head or it can be used at least partially in this and thus leaves room for the shell part.

It is also possible to clamp the clamping springs against an inner wall of the applicator. to be supported onskopfes supported. For advantageous actuation and release of the reservoir by means of the pressure vessel is an adapter piece Betätigungsvorrich ^¬ tung as a screw for biasing and releasing the clamping springs are provided.

These and other advantages are set forth by the following description with reference to the accompanying figures.

The present invention relates to a fluid delivery device 90 as shown in FIG. 6 and particularly suitable for use with pressurized containers such as aerosol cans 30 or to fluid delivery devices constructed using pumps for delivering a disinfecting or conditioning agent liquid, gel, emulsion or other form.

Such embodiments are shown in particular in FIGS. 1a, b and c by the reference numeral 100. The fluid application devices 90, 100 according to the invention are all suitable for automatic fluid dispensing and have an application head 9 'on which a sensor 4 and an outlet nozzle 5 for dispensing fluid are arranged. The nozzle 5 is in each case fluidically connected to a reservoir 30.

In the embodiment for pressure cans shown in FIG. 6, the application head 9 'has on its upper side an integrated dispensing arm, not shown separately, on which the nozzle, not shown figuratively, is arranged pointing downwards. The reservoir 30 is a pressurized aerosol can 30, as shown in Fig. 7a, so that according to this realization of the fluid-idapplikationsvorrichtung can be dispensed with means for conveying the fluid. The cover 16 of the application head 9 'can be pushed up by flanges on the cover 16 and on the head, which form a rail guide as it were. The pushing up can also be done automatically and hydraulically. In this case, a small motor for carrying out the displacement should be provided in the application head 9 '.

In the application head 9 ', however, there is a control unit for sensor-controlled opening and closing of the valve of the pressurized aerosol can 30, which can be seen on the upper side of the can 30 shown in FIG. 7a. The valve is connected via a connecting piece to the nozzle for dispensing the fluid. At the application head 9 'internally a pressure vessel adapter piece is arranged, which serves to hold the pressure vessel 30 in the application device. Such a pressure vessel adapter piece is shown in a simple form in Fig. 7a to 7d: It is designed as a clamp, wherein the clamping bracket 24 has two biased by a respective clamping spring 25 Umgriffelemente 25 ', which are arranged radially displaceably in the frame member 28 and thus pinch the head of the pressure box 8 '. The clamping springs 25 can be supported in the attachment 22 according to FIGS. 7b and c. There are also the actuators, designed here as set screws 26, for biasing and loosening the clamping springs 25 are shown. By turning the screw thus the diameter of the clamping device can be tapered or widened, depending on the size of the pressure to be held, resulting in the adapter function.

7e shows the clamping holder 24 with the clamping springs 25 and the frame part 28 in exploded view, for arrangement in the attachment 22, which is cylindrical and has on its upper side a recess with Abstützflansch 22 ', on which the clamping bracket 24 can be placed. Alternatively, however, the clamping bracket shown in Fig. 7b also directly into the adapter head 9 ' the fluid delivery device as shown in Fig. 6 are used.

The embodiment shown in Fig. 6 further shows a shell piece 9, which basically forms the "housing" of the application device, which is closed in the direction of the operating side and has a cylindrical bulge, on the inside of which the pressure cell can be inserted from below can, is present.

For mounting on the wall, a wall mount 10 is provided on the rear side of the application device 90, here without electronic passages.

Further, Fig. 6 shows a collecting tray 1 1, which is directly cut to the shell portion and serves to collect excess fluid output. It can be used in a simple embodiment doppelbödig with inlaid absorbent, such as pads, which absorb the excess fluid and can be replaced accordingly when the doppelbödige drip tray element 1 1, as proposed for unfolding is designed or at least the extraction and replacement of Pads.

The fluid application devices shown in FIGS. 1 a, b and c, on the other hand, operate with reservoirs 30 ', from which the fluid is pumped by the use of a pump 1, see FIGS. 4 and 5h. In the present case, this is a diaphragm pump 1, which is coupled to a one-way valve 6 and has an inlet which, by means of a piece of tubing, removes the fluid from the inlet. storage vessel 30 ', see Fig. 1 b, promotes. Furthermore, the pump is connected on the outlet side via its connecting piece by means of a hose 5 "fluidically to the nozzle 5, or via the connecting sleeve 5 'on which the nozzle 5 is arranged, see exploded view Fig. 4. The view in Fig. 4 shows a Arrangement variant for the battery magazine 2 in a vertical orientation, not provided for immediate disposition under the cover 16 of the application head The fluid connection at the nozzle 5 via the connection 5 'can also be seen in FIG. 2c and FIG In these embodiments, the application head 9 'has on the upper side an application arm 15 designed as a limb, on the underside of which the nozzle 5 for dispensing the fluid is arranged. As shown in Fig. 1a, a sensor 4 can be arranged on the vertical wall However, the sensor 4 could also be immediately behind the nozzle 5 or in front of the nozzle 5 when using a ande be arranged ren designs. It is also possible to use more than one sensor 4 if correspondingly additional tasks are provided except for triggering the pump with the sensor 4. Further tasks could be, for example, the determination of the body part size or its shape to be disinfected or to be supplied with fluid. In this case, the application head 9 'has quasi-directly by a plurality of optical sensors, which allow reflection measurements, via devices for body part recognition.

As can further be seen, extending from the application head 9 'via an adapter piece 8 a jacket piece 9 downwards, which preferably and in order to provide a suitable optics, the storage vessel at least partially surrounds and advantageous, as in the embodiments of FIG 1 a, b and c, extends to the lower bottom of the storage vessel 30 '. The embodiments shown allow the introduction of the storage vessel 30 'from the front bottom into the Applikati- onsvorrichtung, so that the shell piece 9, the storage vessel 30' respectively engages. From below, the storage vessel 30 'extends as far as an adapter piece 8, which can clearly be seen in FIG. 4 or FIG. 5j. This Adapter piece 8 has an offset from the edge inwardly flange 8 ', which is brought into engagement with egg ^¬ ner opening 18 of the storage vessel. Next, the adapter piece 8 forms a bottom to which the pump 1, see Fig. 5h, as well as a Bat ^¬ teriemagazineehäuse 17 (Fig. 5i) for receiving a battery magazine 2, see Fig. 5f, can be kept, if it is not immediately below the cover 16 is placed lying (Fig. 2e). This floor has a passage opening 18, through which a delivery hose can be inserted.

As FIG. 2c (opened application head 9 ') shows, the battery magazine 2 can also be arranged at the top in the application head 9', the batteries being arranged horizontally. This arrangement of the battery magazine 2 is also shown in FIG. 2d, which also shows the LEDs 21, 21 'for indicating the operational readiness of the device and also the actuating pushbuttons 31, 31' for switching the device on and off, which are also connected to the control and / or or control circuit of the device, suitably via the board 3, are operatively connected.

Also, Fig. 2e shows an insight into the application head 9 'with the LEDs 21, 21', the battery magazine 2 and the electronic terminals of the batteries and the operation buttons 31, 31 '.

The perspective side view of the head of the fluid application device 9 'of Figure 2f provides the connection from the nozzle 5 via the spigot 5' connected to the hose 5 "to the one-way valve 6 and the pump 1 and finally to the Plug 7, which opens into the storage vessel, if necessary via the adapter piece 8, as it is additionally shown in Fig. 2g.In the embodiment shown are also the actuating push buttons 31, 3 'on the board 3 and the LEDs 21, 21st It is proposed that, for a secure and tight holding of the delivery hose, a plug 7 is drilled accordingly, as shown in Fig. 5g, to be inserted into the passage 18. The delivery hose is seated therewith sure in the Bore of the plug 7 and this in the opening 18 of the adapter piece. 8

Incidentally, FIG. 5f shows the sensor 4 as a separate element with the reference numeral 4. In order to be able to remove the components from the application head 9 'in a suitable manner, the application head 9' can be provided with a cover 16. This can be in many different ways, either by engagement by means of flanges shown or by a hinge member, or placed in any other way and connected to the other housing of the application head 9 '. Thus, by simply opening the application head 9 ', the battery magazine 2 can be replaced by removal from the housing 17.

Fig. 5b shows (see also Fig. 4) a board 3, on which a control and regulating unit is arranged, which is in operative connection with the sensor 4. The sensor 4 can, figuratively not shown, be arranged on the underside of the board 3.

If now the sensor is activated, which can be an optical or optoelectronic sensor, and thus detects when the light conditions change, for example triggered by the insertion of a hand under the sensor, the operative connection is started by means of the control and Regulation to operate the pump 1 and causes by opening the valve 6 correspondingly, the conveying of fluid from the storage vessel 30 'and outputting the fluid through the nozzle 5. The control device allows either preset solid output volumes, expressed in ml, to ensure an actuator may decrease a sufficient amount of disinfectant or care fluid, or it may be a control device that operates in response to a hand size or fluid condition associated with hand size or skin texture that may be measured by the opto-electronic sensor; is regulated. Therefore, it is also possible to provide a plurality of sensors 4 in order to visualize the outlines of a hand in a simple manner to determine. Thus, it is advantageously ensured with the invention that a reliable dispensing of disinfectant with respect to the required hand-size-dependent supply is achieved. The circuit board 3 can be protected with a cover 3 ', see FIG. 5a, in the application head 9'.
